public abstract class J2DoPrivHelper
extends Object

Helper class to obtain the Privilege(Exception)Action object to perform Java 2 doPrivilege security sensitive function call in the following methods:

• AccessibleObject.setAccessible
• Class.forName
• Class.getClassLoader
• Class.getDeclaredField
• Class.getDeclaredFields
• Class.getDeclaredMethod
• Class.getDeclaredMethods
• Class.getProtectionDomain
• Class.getResource
• Class.newInstance
• ClassLoader.getParent
• ClassLoader.getResource
• ClassLoader.getResources
• ClassLoader.getSystemClassLoader
• File.deleteOnExit
• File.delete
• File.exists
• File.getAbsoluteFile
• File.getAbsolutePath
• File.getCanonicalPath
• File.listFiles
• File.length
• File.isDirectory
• File.mkdirs
• File.renameTo
• File.toURL
• FileInputStream new
• FileOutputStream new
• System.getProperties
• InetAddress.getByName
• MultiClassLoader new
• ServerSocket new
• Socket new
• Socket.accept
• System.getProperty
• Thread.getContextClassLoader
• Thread.setContextClassLoader
• Thread new
• TemporaryClassLoader new
• URL.openStream
• URLConnection.getContent
• ZipFile new
• AnnotatedElement.getAnnotations
• AnnotatedElement.getDeclaredAnnotations
• AnnotatedElement.isAnnotationPresent
• jakarta.validation.Validator.validate
• jakarta.validation.Validation.buildDefaultValidatorFactory

If these methods are used, the following sample usage patterns should be followed to ensure proper privilege is granted:

 1) No security risk method call. E.g.

    private static final String SEP = J2DoPrivHelper.getLineSeparator();

 2) Methods with no exception thrown. PrivilegedAction is returned from
    J2DoPrivHelper.*Action(). E.g.

    ClassLoader loader = AccessController.doPrivileged(
                             J2DoPrivHelper.getClassLoaderAction(clazz));

    ClassLoader loader = (ClassLoader) (System.getSecurityManager() == null)
                         ? clazz.getClassLoader()
                         : AccessController.doPrivileged(
                             J2DoPrivHelper.getClassLoaderAction(clazz));
 3) Methods with exception thrown. PrivilegedExceptionAction is returned
    from J2DoPrivHelper.*Action(). E.g.

    try {
      method = AccessController.doPrivileged(
        J2DoPrivHelper.getDeclaredMethodAction(clazz, name, parameterType));
    } catch (PrivilegedActionException pae) {
      throw (NoSuchMethodException) pae.getException();
    }

    try {
      method = (System.getSecurityManager() == null)
        ? clazz.getDeclaredMethod(name,parameterType)
        : AccessController.doPrivileged(
            J2DoPrivHelper.getDeclaredMethodAction(
              clazz, name, parameterType));
    } catch (PrivilegedActionException pae) {
        throw (NoSuchMethodException) pae.getException()
    }
